Events and Customization
RadScheduler provides a set of events that allow you to customize the appearance of the printed elements:
FormattingEvents
PrintElementFormatting: Fires when a print element is being formatted before it is printed.
CellPrintElementFormatting: Fires when a cell print element is being formatted before it is printed.
AppointmentPrintElementFormatting: Fires when an appointment print element is being formatted before it is printed.
PaintEvents
PrintElementPaint: Fires when a print element is printed.
CellPrintElementPaint: Fires when a cell print element is printed.
AppointmentPrintElementPaint: Fires when an appointment print element is printed.
Here is an example. The comments are inline:
